From fbb763e7e7366c27848cbfb09d983802b6322709 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Fri, 9 Apr 2021 15:40:23 -0500 Subject: net: ipa: add IPA v4.5 configuration data Add support for the SDX55 SoC, which includes IPA version 4.5. Starting with IPA v4.5, a few of the memory regions have a different number of "canary" values; update comments in the where the region identifers are defined to accurately reflect that. I'll note three differences in SDX55 versus the other two existing platforms (SDM845 and SC7180): - SDX55 uses a 32-bit Linux kernel - SDX55 has four interconnects rather than three - SDX55 uses IPA v4.5, which uses inline checksum offload Signed-off-by: Alex Elder Signed-off-by: David S.
